£300 for sports cat, £379 for cat back system 2.25" pipe, £75 for oval tail pipe. Custom made and fabricated to your car. Longlife/powerflow. Downside very loud at low revs, cant hear it over 3000rpm, also moves the powerbracket up. Basically lose torque low down because of the amount of gasses that are flowing no longer being restricted. Upside pulls so strong all the way to redline, instead of choking up at about 5000rpm. Mint exhaust with plenty of burbles!
